I am wondering how I can add a gallery slider inside one of my tab frames?
Hey tdproperty!
They were not meant to be used like this but you can switch to the default editor and copy / paste the shortcode inside the tab shortcode so it looks like this.
[av_tab_container position='top_tab' boxed='border_tabs' initial='1' custom_class='']
[av_tab title='Tab 1' icon_select='no' icon='']
[av_gallery ids='156,10' style='thumbnails' preview_size='portfolio' crop_big_preview_thumbnail='avia-gallery-big-crop-thumb' thumb_size='portfolio' columns='5' imagelink='lightbox' lazyload='avia_lazyload' custom_class='']
[/av_tab]
[av_tab title='Tab 2' icon_select='no' icon='']
Tab Content goes here
[/av_tab]
[/av_tab_container]
If you want to do it in the advanced layout editor then you can enable the debug view, http://kriesi.at/documentation/enfold/enable-advanced-layout-builder-debug/, and move the shortcodes around in there but it would be best to use the default editor.
